Eh, it also depends on where you live. I don't know what it's like over there, but we have an addiction crisis where I live. People steal many odd things, sometimes because they like them, sometimes to sell them, and other times because they hatch a crazy plan that they give up on halfway through.

We definitely have certain people that are regularly kicked out of stores due to prior misbehaviour. (Assult, theft, biohazard stuff, etc.) Sometimes there's only so much that you can deal with from the same person, you know? It can get to the point where you just ban someone.
